FramePort 1.1.0

Gamepads that appear after the start reach a running 2D app; D-pad buttons in the pad layout (#162 )
Agent 85: the game's container gets the host's /dev/input at /dev/fp-input (Lepton's /dev/input holds its own Wayland input pipes) and the launcher's _gamepad_links worker keeps /dev/input/eventN links to Steam Input's virtual pads in step while the game runs: controllers switched off and on again (Steam makes a new pad) work without a restart. Android's EventHub adds and removes the links through inotify (dev Frame, uinput stand-in pad created after boot: New device, Device removed, added again). Older launchers get the new gamepad line through upgrade_launchers. The key layout also maps BTN_DPAD_* (a Steam Input layout that sends the D-pad as buttons, e.g. a stick set to D-pad; the Frame's controllers have no D-pad of their own).

+notes: >-
+  Headset tested for GitHub issue 61: full view, loading into gameplay, both eyes, controller input and sound
+  work with the splash bypass and multiview depth-size fix. Keep the main OBB and all three content/sound-bank PAKs.
 details: Unreal Engine 4 (GLES) by ILMxLAB, like Vader Immortal, but a different engine build - it has none of Vader's
  Quest-only branches (no GetQuestShaderPrecompilePercent or RPOC key map; it precompiles shaders through Unreal's
  own pipeline cache), so frame.unreal_quest_precompile/_keymap don't apply. Its seasons and Wwise banks are Meta
  platform asset files (frame.asset_files). Vader's OVRPlugin findings apply to it as well - poses asked for at
  OVRPlugin's own clock (pose_time_fix) and thumbs from near-touch, which the Frame never reports (frame.unreal_thumb_touch).
-  Ruled out for the black picture so far (see the diagnostics in issue 61) - asset-file paks, Valve's foveation,
-  GL errors; the game's own eye image reads back black.
+  Map travel stalls with the game thread waiting in FlushRenderingCommands and the render thread waiting in
+  FSplash::RenderFrame_RenderThread / ovrp_WaitToBeginFrame. frame.unreal_splash_bypass lets loading finish.
+  SideQuest backups with sibling apk/ and obb/ folders must include all three PAKs; old scans omitted them and
+  lost sound. The scanner and library refresh recover that layout. Eye clipping came from cached Android window
+  dimensions for the depth attachment (1920x1016 versus the 1728x1728 eye color texture).
+  frame.unreal_multiview_depth refreshes both cached dimensions from the current eye render size; multiview and
+  multisampling remain enabled. The two engine fixes check exported symbols, function sizes and instruction bytes
+  before changing one instruction each; unrecognized engine builds are left unchanged.

-status: unsupported
-notes: Starts and reaches the menu room, but the room shows no controllers and ignores all input (it all reaches
-  the game); no fix yet.
+status: works
+notes: From Klownicle's guide (GitHub issue 57); FramePort's version verified in a Steam Frame headset (2026-10-11).
+  Menus and racing controls, car bodies and controllers, particle effects, the full field of view and a sharp,
+  correctly placed picture.
+details: 'Seven fixes from the guide. frame.blazerush (this exact build only) skips the menus'' wait for a Meta avatar,
+  which never comes on the Frame, so the game creates its own controllers, and gives its shader cache a new folder
+  (cache/br_shader_v1) so programs compiled before the shader fixes aren''t reused. The GL shim feeds integer vertex
+  inputs (bone indices) as integers (gl_int_attribs: car bodies and controllers were invisible) and computes the
+  particle vertex shaders in highp (gl_highp_markers: streaks and flashes). The game reads the field of view once at
+  start, before tracking: the VrApi bridge answers with the FOV of the previous session (FramePort''s launch test
+  after the install is one), not 90x90 degrees. scale 1.7 keeps the wider view sharp (about 2.9x the pixels).
+  device.config_sync keeps the resolution saved in user_config.xml at the eye-buffer size, else the picture is
+  displaced with black borders after a scale change.'

+- **Several backups of one game:** FramePort uses the newest one. To use another, scan just that backup's folder.
+- **AXRB's patched builds** (`patched/`, `*-axrb.apk`) are converted for AXRB's PC runtime and lack the game's data, so
+  FramePort skips them and, on the next scan, replaces a game that was added from one with the original download.
+- **AXRB export ZIPs:** unpack them first. A game's ZIP holds `base.apk` and `Android/obb/<package>/`, which FramePort
+  finds as is.
+- **"Game data (.obb) is missing" on the game's page** although you have the file: the backup didn't include it (copy
+  the game's `Android/obb/<package>` folder from the Quest with SideQuest), or it sits in a folder FramePort doesn't
+  look in. Then use the layout in the previous answer.
+- **The game starts and stops at once (Steam shows Resume):** add the game again from its original download or
+  backup, click **Update on Frame**, then report it (last answer on this page) if it still stops.
+
+## Where are a game's settings in FramePort?
+
+Every game has three places; the answers below refer to them.
+
+- **Game settings:** right-click the game in the **Library** → **Game settings…**. Sharpness, refresh rate,
+  controllers, menus and more, in plain words. Changes apply the next time the game starts.
+- **Patches:** click the game in the **Library** to open its page, then **Customize** (in the **Patches** section).
+  Turn a patch on or off, then click **Update on Frame** at the top of the page.
+- **The game's menu:** the **…** button at the top of its page (or right-click in the Library → **More actions…**).
+  It has **Reset to suggested recipe…** and **Report a problem…**, among others.
+
+The sidebar has two tabs for troubleshooting: **Monitor** (the running game's frame rate, CPU and graphics) and
+**Files** (each installed game's storage on the Frame, under **Game storage**).
+
+## A game doesn't work right. Where do I start?
+
+1. **Update FramePort** (it offers updates itself; Settings → Updates), then open the game's page: if it shows
+   **Update on Frame**, click it. Recipes and patches improve often.
+2. **Read the game's page.** The last launch test and your last play session (**Last session**) leave their result
+   there, often with a suggested patch or setting and a button that applies it. Try that first.
+3. **Changed patches yourself?** The game's menu → **Reset to suggested recipe…** brings back the tested ones.
+4. **Find your symptom below.** Each answer says how to tell what's wrong and what to do.
+5. **Still stuck?** Report it (last answer on this page).
+
+## The game doesn't start, or stops right away
+
+How to tell: the game's page shows the last launch test's result (**Last launch test:** …) with an explanation, and
+Steam returns to **Play** or **Resume** within seconds.
+
+- **"Game data (.obb) is missing"** on the game's page: FramePort didn't find the game's data files, so they never
+  reached the Frame.
+  1. Find the game's `.obb` files (named like `main.<version>.<package>.obb`).
+  2. Put them in a folder named exactly the package name (shown in the file names) next to the game's APK, as in the
+     first answer on this page.
+  3. Library → **Add games** → **Scan a folder…** and pick the game's folder.
+  4. Open the game's page and click **Update on Frame**.
+- **"Lepton didn't start the game this time"**, or it failed only on the first start after an install: click **Play**
+  again.
+- **"This game is 32-bit only"**: the Frame can't run 32-bit apps, and no patch changes that. Look for a PC VR version
+  of the game.
+- **"The game quit itself right after starting"**: open the game's page and click **Update on Frame** so the suggested
+  patches apply (many games check for a Quest at start, and a patch removes that).
+- **Nothing like that, or it still fails:** report it.
+
+## It hangs on a logo, a black screen or a loading screen
+
+How to tell what it's doing: leave it running and open **Monitor** in FramePort's sidebar.
+
+- **CPU or graphics busy:** it's still working, often preparing its shaders on the first start. Wait up to 10 minutes
+  once; the next start is quicker.
+- **CPU and graphics near zero:** it's stuck waiting for something. While it still hangs, open the game's menu →
+  **Report a problem…** and save the diagnostics: that zip shows what each of the game's threads waits for (FramePort
+  1.0.1 and newer), which a zip saved after quitting can't. Attach it to the report.
+- **The game starts with a video** and hangs at its logo: game page → **Customize** → turn off **Hardware video
+  decoding** → **Update on Frame**, and try again.
+
+## The picture is wrong
+
+Most picture problems have a setting or a patch. Change one thing at a time, then start the game again (patches also
+need **Update on Frame**).
+
+| You see | Try |
+|---|---|
+| Something shows in one eye only, or one eye is gray (Unity games) | Game page → **Customize** → [Unity: render each eye separately](PATCHES.md#frame-unity_multipass) |
+| Left and right look swapped (depth feels wrong) | **Game settings…** → **Swap eyes** |
+| Textures flicker, objects pop in and out | **Game settings…** → **Turn off space warp** |
+| One eye shimmers while menus look steady | Game page → **Customize** → **Eye-tracked foveation (Valve)**: **Fixed**, else **Off** |
+| Menus or screens upside down | **Game settings…** → **Fix upside-down menus** |
+| Curved menus or video screens missing | **Game settings…** → **Show curved menus and screens** |
+| Blurry | **Game settings…** → raise **Sharpness** (costs frame rate) |
+
+The [patch reference](PATCHES.md) lists every patch with what it does. If nothing helps, report it with a short
+description of what you see.
+
+## It stutters or runs slowly
+
+How to tell: open **Monitor** in the sidebar while you play. Smooth play needs the game's frame rate at the refresh
+rate (for example 72 or 90 fps).
+
+- **Below the refresh rate:** right-click the game → **Game settings…** → lower **Sharpness** (for example to 0.8×) or
+  pick a lower **Refresh rate**. After a session, the game's page may suggest a value.
+- **At the refresh rate but it still judders:** report it; that points to timing, not speed.
+
+## The game pauses or recenters by itself
+
+The Frame briefly tells games they lost focus, for example when the headset's sensor thinks you took it off.
+Right-click the game → **Game settings…**: keep **Don't pause on short interruptions** on and raise **Ignore focus
+dips up to** (for example to 2.5 s).
+
+## Controllers don't work in a game
+
+Right-click the game → **Game settings…**:
+
+- **No controllers, or only hands:** turn on **Use controllers**.
+- **Buttons work but you can't aim at menus:** adjust **Pointer angle**.
+- **Vibration too strong:** lower **Vibration strength**.
+
+## The Frame turns off or gets hot during a game
+
+How to tell: if it only happens on battery and never while plugged in, it's power, not FramePort. Heavy games can
+draw more than the battery delivers, especially at lower charge, and the Frame then turns off without an error.
+
+- Play plugged in, or right-click the game → **Game settings…** → lower **Sharpness** to reduce the load.
+- It also turns off while plugged in: report it. The diagnostics include the log of the boot that ended.
+
+## My progress isn't saved
+
+1. Quit through the game's own menu, not Steam's **Exit game**. Exit game closes the game at once, and some games only
+   save when they exit normally.
+2. Check whether it saves at all: **Files** in the sidebar → under **Game storage**, the game → look at the files'
+   dates. Play, save in the game, quit from its menu and look again.
+3. Nothing changes: report it.
+
+Saves stay on the Frame when you update or reinstall a game.
+
+## A game with mods crashes
+
+How to tell: play once without mods and custom content. If it then works, a mod is the cause; the diagnostics zip
+usually names the mod's library in the crash. Report it to the mod's author, and check for a mod version that matches
+your game version.
+
+## The game needs files I supply (ports, emulators, mods)
+
+How to tell where they go: the game says it on screen or in its instructions, and its log names the path (in the
+diagnostics zip, `launch.log`). It's usually `Android/data/<package>/files`.
+
+1. Unpack or extract the files on your PC first: these apps read folders, not disc images (`.iso`) or archives.
+2. **Files** in the sidebar → under **Game storage**, the game → open that folder → **Upload folder…** (or
+   **Upload files…**). The game's menu → **Add videos and files** opens the same place.
+
+In-game "choose a file" buttons don't work on the Frame, which has no file picker.
+
+## How do I report a problem well?
+
+1. Reproduce it once, then right away open the game's menu (**…** on its page) → **Report a problem…**. For a hang,
+   do it while the game still hangs.
+2. Say what you saw in the headset and what you already tried.
+3. **Collect and open GitHub** saves a diagnostics zip and opens a prefilled game report; attach the zip to it. The
+   zip holds logs, not your game files, and personal details are removed.

+not all Quest games or renderers. RE4 and Batman checks include title/calibration scenes; these are not
+equivalent to extended gameplay coverage. Asgard gameplay was visually confirmed, without an on/off benchmark.
+Batman additionally receives the verified ordinary shared-allocation patch, guarded by the full original
+OVRPlugin hash; unknown Batman versions fail explicitly rather than receiving unchecked binary offsets.
+
+The Climb 2 uses a private `libvrapi_foveation.so` bridge, installed only into that game's APK after the
+standard bridge patch. It retains images during held-focus visibility dips, separates mono overlay output
+storage from stereo density-map storage, and rate-limits its view-cache writes. Its process-local Valve layer
+correction supplies both eye offsets and avoids the invalid subpass mask-table reads seen during Alps loading;
+`yflip` corrects vertical gaze direction. The renderer SHA-256 and 1.0 resolution scale are checked before
+installation. The runtime correction additionally checks the exact Valve library SHA-256 and all four original
+instructions before touching executable memory; unsupported libraries request injection be disabled and log
+the reason. No system library is changed. A SteamOS update requires revalidation of this compatibility path.
+Both-eye gaze following was confirmed in Climb's darkening diagnostic, but long-session stability remains
+experimental. Off rebuilds from the source APK and removes this private support, including its visibility fix.
+
+**Darken lower-resolution regions (test)** adds an optional Vulkan shader diagnostic. It dims RGB where the
+actual `FragSizeEXT` footprint exceeds one pixel; alpha is unchanged. Deadpool's shaded regions were confirmed
+to follow gaze in the headset. Unsupported shader output interfaces are skipped, and multiple passes may
+compound darkening, so this is a diagnostic rather than a precise composited mask. Do not benchmark with it on.
+Uncheck it and update from the original source APK to remove the diagnostic library, except in Climb where
+the same library also carries the compatibility correction. Darkening stays dormant without its launcher opt-in.
+
+High-resolution Deadpool samples crossed from about 45 to 90 FPS with injection enabled, but temperatures and
+power rose as it rendered twice as many frames. Foveation does not guarantee lower temperature at uncapped FPS.
+The new configurable radii have configuration/build coverage; each radius has not been separately play-tested.

The VrApi bridge can't replace it (39 of the loader's 114 functions: OVRPlugin wouldn't link) | `frame.vrapi_stub` (same exports, each returns 0); triage `vrapi-before-init` |

Tales also needs the splash and depth-size fixes below |
+| A SideQuest backup has `apk/` and a sibling `obb/` with content/sound-bank PAKs, but the Frame only has the main OBB (GitHub #61, Tales from the Galaxy's Edge) | older scans treated that layout as loose expansion files and selected only the named OBBs; the asset-file patch then found no PAKs | the scanner chooses the OBB folder by version first, then keeps the whole sibling data folder when all its expansion files are selected for this APK; app updates repair affected library entries and refresh asset/language-pack detection. Reinstall to copy the missing files, or scan the backup again first. Folders with other packages or unselected OBB versions still send only the selected OBBs |

Checks the exported symbol, function size and surrounding instructions, then replaces only the branch that skips refresh. Keeps multiview and multisampling. Headset test: full view and gameplay work |

Lambda1VR's TBXR doesn't even enable `XR_KHR_opengl_es_enable` (only `XR_EXT_local_floor`) | FrameBridge adds `XR_KHR_opengl_es_enable` when an app enables no graphics API extension, asks for the requirements on the game's behalf and retries xrCreateSession once (logs `added XR_KHR_opengl_es_enable …`, `the app skipped …; asked for it`; every launch logs the final extension list `xrCreateInstance with N extension(s)`); triage `graphics-requirements-missing`.

 | Frame freezes or the game is killed (OOM) on the first controller vibration (for example Lucky's Tale's save slots, BattleSisters, Sniper Elite VR's tutorial grab: memory grows ~1 GB/s until the kill) | OVRPort runtimes up to 3.4.3-23204ea read the haptic envelope's duration (ns) as seconds and allocate gigabytes of samples (GitHub #9, ovrport/app#73); also reached from Unity's legacy `ovrp_SetControllerHaptics`; perf page faults all in `libopenxr_loader.so` `xrApplyHapticFeedback` | `adapter.haptic_fix` (envelope → one plain vibration in `native/xrshim`; PCM vibrations (`XrHapticPcmVibrationFB`) are converted the same way). Fixed in runtime 3.4.3-aa54c3f: builds made with it leave the workaround out by themselves (log "not needed: adapter.haptic_fix", `frameport show` "last build left out"); rebuild an older build to switch |
 | Controller vibrations much stronger than on a Quest (The Boys VR, Jurassic World, BONELAB, …) | OVRPlugin games send amplitude envelopes; `haptic_fix` turned each into one vibration at the envelope's *peak* for its whole duration (a short fading pulse became a long full-strength buzz) | `haptic_fix` now uses the envelope's RMS; Game settings → "Vibration strength" (`haptic_scale`, 0-1) scales every vibration in FrameBridge; launch.log shows the first requests (`haptic: …`). OVRPlugin stops a vibration with amplitude 0 (2 s duration): FrameBridge turns that into xrStopHapticFeedback (without it the last buzz ran its full 2 s) |
 | Play or a launch test fails at once: `Game files missing at <path> (storage not mounted?)` in launch.log, or "… files are on a drive that isn't inserted" (GitHub #90) | the game was installed or moved to a microSD card (`<mount>/FramePort/<pkg>`) that isn't inserted or mounted now | insert the card; or move the game back (game menu → Move to…, `frameport frame move <pkg> --to internal`) once the card is back. `frameport frame drives` shows what the agent sees (exFAT/NTFS cards are refused: format in SteamOS) |
 | A Linux app started from Desktop Mode's menu closes after ~2 s, or opens on the wrong display (GitHub #84) | its launcher predates agent v63: the "Steam parent gone" watchdog ended it when Plasma's launcher exited, and it took gamescope's DISPLAY from Steam | connect FramePort once (agent v63's `upgrade_launchers` adds the `FRAMEPORT_DESKTOP` checks; the menu entry runs `env FRAMEPORT_DESKTOP=1 <anchor>/launch.sh`). Game Mode controller problems in such apps are Steam Input's (a separate issue) |
 | A Linux app (AppImage) shows no/FramePort's placeholder icon in Desktop Mode or Steam (GitHub #99) | before agent v64 only FramePort's art set's icon was used, and a lone AppImage has no store art | connect FramePort once (agent v64 copies the app's `.DirIcon` / `.desktop` `Icon=` to `<anchor>/artwork/app-icon.*` and refreshes the menu entry); reinstall to also get it into the library + Steam shortcut. Still the placeholder: check `<base>/app/squashfs-root/.DirIcon` and the `.desktop` file's `Icon=` (an icon outside the app folder or only an XPM isn't used); a chosen icon (`artwork/.icon-source` = `custom`) always wins |
 | An overlay app (fpsVR, a wrist watch) installed on the Frame never appears, or SteamVR doesn't start it | not registered with the Frame's SteamVR, or registered with a manifest SteamVR skips: on the Frame vrserver reads only `binary_path_linux_arm` (vrserver.txt: "must specify binary_path for launch_type binary. Skipping") | `pcvr.vr_overlay` (Windows) / a Linux app with a bundled `.vrmanifest` (`is_dashboard_overlay`): agent v75 `register_vr_overlay` (check `vrcmd --overlays`, `~/.config/openvr/config/appconfig.json` manifest_paths); the app's own `--install` writes binary_path_linux only. fpsVR under Proton never loads OpenVR (quits after 60 s): unsupported for now |
+| An overlay app with **Start with SteamVR** on doesn't start by itself after the Frame or SteamVR starts (it works when started by hand) | SteamVR's own auto-launch flag (SetApplicationAutoLaunch) didn't persist on the Frame (no autolaunch entry in `~/.config/openvr/config/steamvr.vrsettings`) | agent v76: FramePort's service `frameport-vr-overlays.service` starts it at every new vrserver. Check `systemctl --user status frameport-vr-overlays`, `~/.local/share/frameport/vr-overlays.log` (`new SteamVR (vrserver N)` → `<pkg>: started` / `running` / `couldn't start it: …`), the deployment's `overlay.autostart`, and that `~/.local/share/frameport/vr-overlays.disabled` doesn't exist; `frameport frame info` (ensure_host_fixes) installs a missing service |
 | Every game suddenly fails to start: `crun: create keyring …: Disk quota exceeded`, `is not a running context` | rootless podman leaked a kernel keyring per launch; 200-key quota exhausted | `keyring = false` in `~/.config/containers/containers.conf` (FramePort agent does it), then reboot the Frame once |
+| Launch test "failed" although the game runs in the headset: frames paced, then `OVRPortVrApi: EnterVrMode: no tracked head pose before deadline`, then a crash (e.g. `zink: DEVICE LOST` + SIGSEGV in a `gdrv` thread) (GitHub #57, BlazeRush) | the VrApi bridge ends the VR session after 30 s without head tracking, which only happens without a worn headset; the game's renderer then crashes while tearing down | none needed: launch tests (`triage(..., headless=True)`) treat an exit or crash after a `headless_end` line (catalog/triage.yaml) as a pass when frames were paced before it (info finding `headless-end`); play sessions ignore it. Add new such markers to `headless_end` |
+| Launch test EXITED, launch.log has `Target app (<pkg>) did not start` and no `Start proc …:<pkg>` (GitHub #179) | Lepton occasionally doesn't start the app on the first start after an APK change; Android's `WebViewLoader-: System.exit` at boot is not the game (triage `app-not-started`) | start it again |

 ## Stable composition

+Adapter-owned video outputs explicitly request a static
+`XR_FOVEATION_LEVEL_NONE_FB` runtime profile before image enumeration. This
+prevents shared Valve foveation from coarsening the side-by-side video output.
+The profile applies only to those outputs; application eye swapchains retain
+foveation and gaze tracking. The runtime result is logged as
+`surface_video: full-rate runtime profile result=...`.
+
+Composition retains the original raster pipeline, linear-light blending and
+sRGB colour attachment. A compute compositor was also tested, but did not alone
+fix pixelation and added a private full-size image copy. The full-rate runtime
+profile fixed pixelation in the headset; the restored raster path was confirmed sharp and improved in-game presentation
+from roughly 40–44 to 65–71 FPS in the sampled cutscene. It still needs further
+performance work. Fully opaque video pixels skip the invisible scene texture
+sample and colour transform; partially transparent pixels retain the full blend. The next live cutscene run reported about 84 FPS across its first five post-startup samples, versus about 69 in the preceding run, with decoding steady at 60 FPS. These separate samples do not control for head motion or temperature; smooth playback is not yet fully established. The video surface patch revision marks affected
+recipes for rebuilding without forcing unrelated game updates.
+
+Once native video composition is active, the compositor can sample an sRGB view
+of the worker's shared hardware buffer directly. The renderer retains the slot
+across repeated frames; replacement queues a foreign-queue ownership handoff
+behind earlier compositor reads, and only its signalled fence makes the old slot
+reusable by the worker. Missing compatible views and initial/fallback presentation
+retain the copy path. The full-rate video profile and output resolution are
+unchanged. Deployment/performance validation is initially limited to Batman.
+The headset playback check confirmed good performance, and the live log confirms
+`direct shared-buffer sampling; cache copy skipped`. During active video,
+recorded application pacing was approximately 105–107 FPS, with decoding around
+60 FPS and visible-view GPU waits around 4.0–4.8 ms, versus roughly 6 ms in the
+preceding copy-path run. These are separate live runs, not a thermally controlled
+benchmark. The 8192x4096 decoded input and 2560x2560-per-eye output are retained;
+other games have not been redeployed or performance-tested with this change.
+
+The native GPU fixture checks stereo pixels, fades, image orientation, colour
+transforms, held frames and teardown, plus single-pixel alternating detail across
+both eyes including edges and corners. This is a compositor regression check;
+in-game playback with injection still needs visual confirmation on the headset.

+The native video adapter also preserves Batman's fully black loading state.

This library becomes the loader's first DT_NEEDED; the loader's own exports of the 31 functions it defines are made STB_LOCAL in `.dynsym` (`elf.hide_exports`, nothing moves), so symbol lookups reach the library first. It serves `<tag>.lang` files found in the game's OBB / app files (`$FRAMEPORT_LANGPACK_DIRS` overrides the search path) through `ovr_LanguagePack_*`, `ovr_AssetFile_GetList` (the loader's list + the packs) and `ovr_AssetFile_StatusById`; its own message queue is merged into `ovr_PopMessage`, and every handle that is not ours (an address-range check) goes to the loader's original function, whose address is read at run time from the loader's in-memory `.dynsym`. With patch `frame.asset_files` (marker byte `@FPASSETS@`, or env `FRAMEPORT_ASSET_FILES=1`) it also lists the data's `*.pak` content files as installed `default` asset files and answers `ovr_AssetFile_DownloadById` for them at once (a completed `DownloadUpdate`, then the result with the path).

The engine library gets it as first DT_NEEDED (direct `gl*` imports) and its `dlopen("libGLESv3.so")` string is rewritten to `libfpglmv.so` (same length; its `qgl*` dlsym table); linked `--no-as-needed` to libGLESv3 so dlsym on its handle finds everything it doesn't wrap. It records stage sources at glLinkProgram, caches the draw framebuffer's color-attachment view count per bind, and when a multiview program draws into a 0-view framebuffer it binds a lazily built twin (`glmv_rewrite.h`: num_views layout blanked, `gl_ViewID_OVR` -> `(0u)`; attribute locations + uniform block bindings copied, default-block uniforms copied before every such draw with a shadow to skip unchanged ones), draws, rebinds the original.

The engine library loads it first (DT_NEEDED); its constructor puts the layer in front of Android's GraphicsEnv debug layer list (private Android 11 `getDebugLayers`/`setDebugLayers`, found through libvulkan.so's dependencies) before EGL starts, so the loader picks it up from the app's lib dir.

Also emulates `xrConvertTimespecTimeToTimeKHR`/`xrConvertTimeToTimespecTimeKHR` if the runtime refuses them (the Frame's Android runtime does; its Linux runtime, used by Proton, supports them as of 2026-09-29 — so this part is only a fallback; Proton's wineopenxr needs them for `XR_KHR_win32_convert_performance_counter_time`, which Revive requires) with the adapter's xrWaitFrame-calibrated offset, and drops the extension from xrCreateInstance if the runtime rejects it. Enabled per game by the Proton launch.sh (`XR_API_LAYER_PATH`, `XR_ENABLE_API_LAYERS`). `tests/test_xrlayer.py` builds it for x86_64 and drives it via ctypes. |
 | `oculushmd/` | `win-x64/fp_oculushmd.exe` | PC VR counterpart of overport's `patch_oculus_unreal` (patch `pcvr.oculus_unreal`, default for Unreal Rift games on the Frame). Unreal's OculusHMD and LibOVR's `ovr_Detect` only start when the Windows named event `OculusHMDConnected` exists and is signalled (the Oculus service creates it). `fp_oculushmd.exe <command line>` creates it (manual reset, signalled), runs the command (Revive's injector) in a job object and keeps the event until every process in the job — the game and its children — has exited (fallback without job support: 3 minutes); returns the command's exit code and logs `FramePort oculushmd: …` to stderr (launch.log). Freestanding Windows x64 console exe (no CRT, no Windows SDK): the NDK's clang + `lld-link /Brepro` with a kernel32 import library generated by `llvm-dlltool`, so it's byte-reproducible. Tested on Windows from WSL with a build whose event name is `-DEVENT_NAME=L"…"` (the Oculus service owns the real event on a PC with the Oculus app). |

+// 1 on its projection layer) showed the level loading on the Frame instead of black. With the setting, FrameBridge
+// draws the fade itself: a black, alpha-blended quad layer right in front of the eyes (VIEW space, 1 m ahead, far

+// projection layers, which is what a fade needs; it is inserted right after the dimmed projection layer, so the game's
+// own quads (loading icons, subtitles) stay on top of it.
+//  * No drawing per frame: one tiny swapchain, refilled only when the fade level changes (at most FADE_LEVELS small
+//    clears per fade: Vulkan vkCmdClearColorImage on the app's queue through flip_vk.c's command buffer; GLES glClear
+//    through a temporary framebuffer in the app's current context). A swapchain's last released image stays valid
+//    for every later frame. (One swapchain per level hit XR_ERROR_LIMIT_REACHED in Batman: the Frame's runtime
+//    allows only a few swapchains per app.)
+//  * Set up on the first frame that needs it; any failure turns the fade off for the session (logged once).

+// Frame the libraries Lepton and FramePort add (Mesa/Zink, FrameBridge, OVRPort's dispatcher, Valve's Vulkan layers)
+// take more than on a Quest. Games with many other native libraries then run out: Wander 0.3570 (Gecko, avatar
+// libraries, Firebase) aborted in Firestore's start with "cannot create thread specific key for __cxa_get_globals()".
+//
+// FramePort renames libunity.so's imports pthread_key_create/_delete and pthread_get/setspecific to the fp_tkey_*
+// functions below (same strings, shorter, NUL-padded) and adds this library to its DT_NEEDED. Keys without a
+// destructor become slots in one per-thread table that lives under a single real key; keys with a destructor, and
+// every other library, keep using real keys. Approach and the original helper: Klownicle (GitHub #198), verified in
+// the headset; this is FramePort's own implementation of it.
+//
+// Pooled keys are TAG + slot (bionic's own keys have bit 31 set, so the ranges can't meet). A slot's generation
+// changes at every create, so a value stored under a deleted key isn't seen through a new key that reuses the slot.
